SCUDDING ATTACHMEIN' T TO FELT AND HIDE WASHING OR EATING MACHINES,

Specification of Letters Patent.

Application filed September 5, 1917. Serial No. 189,720.

To all whom it may concern Be it known that I, VVILLIAM Cox, -sub ject of the King of Great Britain, residing at Petone, Wellington, in the Dominion of New Zealand, have invented a new and useful Scudding Attachment to Pelt and Hide Washing or Rating Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention hasbeen designed in order to provide an attachment for the wellknown construction of pelt and hide washing or baiting machines in which a rotating dolly, or series of radiating beater arms, is employed to agitate the pelts or hides contained in the washing'or'bating fluid. The object of the attachment is to subject the pelts or hides to a scudding treatment during the washing r bating operation.

His generally customary in the treatment of animal hides or pelts, in order to remove any flesh or other matter adhering to their surfaces, to subject them to a scudding or scraping operation usually erformed by hand and by the employment of special scudder or scrap er knives. The present invention dispenses with this hand treatment, and provides for the scudding or scraping operation upon the pelts, being performed during the washing or bating operations to which they are sub ected in the machine referred to.

To efl'ect the object of my invention a beater or scraping bar, formed with one or more edges extending longitudinally along its bottom, is so arranged within the tank of the machine as to extend in a position adjacent to the dolly so that in the rotation of the dolly the latter will cause the pelts or hides to be moved across the scraping edge or edges of the attachment. The bar is preferably suspended within the machine in such a manner that it may be swung up out of use whenever required.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a cross sectional elevation of a machine with the attachment in position therein. 7 v v Fig. 2 is a front elevation thereof, the tank being shown in section.

Fig. 3 is a cross section, on an enlarged scale showing the construction of the beater or scraping bar and also the means for mounting it in the machine.

Fig. 4 is an elevation of an alternative form of scraper bar.

A is the washing tank and B the rotating dolly mounted therein. These are of the ordinary and well known construction.

' C is the beater bar or scraping bar constituting this invention and which is formed in any suitable manner such as to provide one 0r more serrations or teeth D extending along its bottom edge. Two of these teeth are shown in the drawings in which the bar represented is made of wood and the teeth provided with strips E of metal, such as steel secured along their faces to form the actual scraping edges. The working edges of these strips may be made plain as shown in Fig. 2, or scalloped or serrated as shown in Fig. 4.

The bar is arranged parallel with and adjacent to the dolly B so that in the working thereof, the pelts or hides will be drawn across the edges or teeth and subjected to a scraping or scudding action such as to dispense with or reduce the separate scudding treatment to which such pelts or hides have at present to be afterward subjected.

As will appear from the drawing, the rotation of the dolly will cause its heaters to engage the hides or pelts, which are kept agitated and moving by the flow of water through the tank A, so that the heaters will grip them and drag their surfaces across the scraping edge of the bar C.

It is well known that in the operation of these appliances a constant stream of water is led through the washing tank, entering over the right edge (according to the drawings) and passing down around the bottom and overflowing the left edge. This serves to wash the pelts or hides toward the left edge. The dolly rotates in a reverse direction 2'. e. from left to right on the lower portion of its rotation so that its heaters grip the pelts or hides as they rise with the water current, and draw them across to the right hand side again. These operations are con: tinued repeatedly. The bar C then engages the pelts or hides as they are gripped and drawn across by the dolly boaters, the upward floating action of the water current ke'eping)them in contact with the scraping edges and the heaters dragging them across such edges. In this manner, the pelts or hides are scraped as desired.

The bar C is preferably so mounted that it may be swungup out of the way, whennot required to, be used, or when the machine is being. filled or' emptied. This is efi'ected by Patented June 3, 1%)

suspending it by means of straps F from the rod G that extends along the machine. The rod passes through the'end plate of the machine at each end thereof and is supported in an adjustable bearing H so disposed and constructed as to permit of the rod being adjusted to any desired height. Each strap F is formed with an elongated eye F through which the rod G passes so that the bar C may be raised and then turned up and over to rest upon the supports J on the insides of the respective machine ends, as indicated by the dotted lines in Fig. 1, Whenever required. Stops K are also provided on the insides of such ends, to engage the bar C when it is down and prevent it swinging into contact With the dolly.

If desired each of the arms of the'dolly B may be provided with a plate B secured along its forward face and projecting beyond its edge so as to form a scraping edge. This edge may be sharpened and corrugated similarly to the plates E, and thus provide for the machine being used for de-hairing hides, as Well as for the other purposes specified.

tudinally of the machine adjacent to and 30 parallel with the rotating dolly or beat ers, such bar belng formed with one or more scraping edges along its bottom, substan-e i lially as and for the purposes herein speci- 2. An attachment as specified in claim 1, in which the bar is suspended to hang upon asupport carried by the machine so as to be su fing into and out of operative position at W1 3. An attachment as specified in claim 1 in Which a support is provided in the machine for maintaining thebar in its inoperative position out of the path of the operating parts of the machine.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
